Problems solved by technology

One problem inherent in such known drain seals is that the seals are opaque, and therefore it is impossible to ascertain if the drain has been completely sealed.

Embodiment Construction

[0009]The invention in various embodiments is a mat-like sealing member 10 adapted to temporarily seal a floor or ground drain, the periphery of the drain seal 10 being chosen to extend beyond the periphery of the drain. The term “mat” or its derivatives is taken herein to reference a thin object of little height relative to its length and width dimensions, and composed of material possessing a flexibility or conformability such that the sealing member 10 is not self-standing when stood onto one of its edges. The drain seal 10 may possess a peripheral configuration of any shape, although rectangular, square or circular are likely to be most suitable. The drain seal 10 is composed of a flexible, compressible, conformable polymer material, impermeable to liquids, such as for example polyurethane, and having sufficient tackiness to conform with the ground or surface surrounding the drain and / or the surface of the drain itself to preclude passage of liquid under the seal and into the dr...

Abstract

A mat-like drain seal composed of a flexible, compressible, conformable polymer material and having at least a centralized window area and a reinforcing band positioned adjacent the edges of the drain seal, the window area being at least translucent such that liquid passing under the drain seal is visible through the drain seal.

Description

[0001]The benefit of U.S. Provisional Patent Application Ser. No. 61 / 752,641, filed Jan. 15, 2013, is claimed.BACKGROUND OF THE INVENTION[0002]This invention relates generally to the field of flat, mat-like seals used to temporarily seal a floor or ground drain to prevent passage of liquid into the drain.[0003]Floor or ground drains are provided in many settings to allow liquids to pass into removal conduits. Often, as in the case for example of storm water drains located along roads and other paved surfaces, the drains empty directly into the storm water system. In the event of hazardous spills, construction run-off or other situations where it is desirable to prevent liquid from entering the drains, it is known to provide sealing mats that are placed atop the drains to block the liquid. The drain seals are typically composed of a flexible, compressible polymer material, such as urethane, having some degree of tackiness and conformability to improve adhesion of the seal to the drai...
